Characters of Mesoscale Convective Complex Development in Korean Peninsula

Heavy rain fall in the Korean Peninsula often ours in the summer season due to MCC (Mesoscale Convective Complex) with complex mechanism. We analysed the Characteristics and the developing mechanism of MCC occurred at 14 July 2004. The results are as follows: a) There is strong wind inflow from the South-west china sea with heavy moisture and this moisture flux acts as the source of heavy rain, b) Because of the separation of upper and lower atmosphere due to an inversion layer at 600hPa. atmosphere over the Korea Peninsula is suddenly unstable. c) This MCC shows strong shear not with wind direction, but with the wind speed, and this wind shear continues the thermodynamic unstability of the convective system. d) MCC was suddenly developed over Henksando at 1400L-ST 14 July 2004. Thus we can say that the topography also was strongly associated with the development of MCC and it is also necessary to clarify the relationship between topography and MCC development in future research.
